Experimental setup for in-vivo testing. A multi-channel concentric cuff was interfaced to the sciatic nerve of a rat. The electrode consisted of three concentric triplets for a total of nine electrodes, and eight of the nine electrodes (solid circles in inset) were connected to the neurostimulator chip. Microwires were inserted into two muscle groups (tibialis anterior and gastrocnemius) to record intramuscular EMG in response to stimulation.
